Stable update: New features, updates, fixes & more.
Well, you said you had backups. If you broke backups too then of course it wont work.
I got my projects broken like 10+ times at this point (4 years of using C3) and I fixed them all myself. Tools like Github can help, because you can specifically see what was changed. Consider using it in future. Or at least clone your backups before trying them, so you wont break them too. And you can use tools like WinDiff to compare backup and the project to see the changes too.
So yes, that's why I'm saying that you too tragic, because you can always fix your projects even without asking the devs, even if you dont have backups. Often times you can figure out whats wrong just from the errors, though its harder
